ioctl: print private SIOC* ioctl commands

Browse Source 
* ioctl.c [!SIOCPROTOPRIVATE] (SIOCPROTOPRIVATE): New macro constant.
[!SIOCDEVPRIVATE] (SIOCDEVPRIVATE): Likewise.
[!SIOCIWFIRSTPRIV] (SIOCIWFIRSTPRIV): Likewise.
[!SIOCIWLASTPRIV] (SIOCIWLASTPRIV): Likewise.
(ioctl_decode_command_number) <SOCK_IOC_TYPE>: Handle protocol-private
and device-private ioctl command numbers.
<0x8B>: Handle device-private ioctl comamnd numbers.
* tests/ioctl.c: Add checks.
